Thanks! I was reading this thread back and forth already, wishing I've got an IFEL board to begin with. Overclocking is not currently the priority, but 4M is the goal. Desperately want to run ADFFS on top of Universal Boot!

OK, re the problems I'm having with 4Mb Memory upgrades not working I have a solution which should solve this problem. I'm away for a week from this Friday (29-09-17), so will sort everyone out when I get back.

I 'may' also have a solution for other machines in the Archimedes range

Hi Dave,

Do you have any of the 4Mb upgrades left please?

I've just got myself an A3000 to add to the collection and would like to max out the ram.

A quick update . . . All ZIP DRAM has now been tested. I need to get my A3000 up and running now to ensure what I send out is good.

Bad news . . . My 93 year old Dad is a bit poorly at the moment and is going through some severe hospital treatment. So, for at least the next week I'll be in Portsmouth (Bosham, actually) in the caravan. The one week may (?) turn into two weeks, so I won't be able to continue this until I get back. Sorry guys . . .

Dave H

Edit: I won't be back until the 12th November . . .

The Archiology site had some test routines for Arcs, from discs that Acorn provided to dealers/engineers. https://www.4corn.co.uk/aview.php?sPath=/archiologyBut AIUI POST testing does check RAM (and took noticeable longer on A3000 with 4MB/ARM2 vs 1MB/ARM2 or 4MB/ARM3, and the A540 lags on startup with 16 vs 4MB).
